Integrated Stereo Amplifier

Elite Integrated Amp Brings Your Music to Life

Built to exacting standards by—and for—genuine music lovers, the A-9000R offers a unique combination of performance and versatility. As one of Onkyo’s new Reference series hi-fi components, the A-9000R shares an advanced design DNA with its sibling models. Like the M-5000R power amp, it includes AWRAT, quad push-pull amplification, and three-stage inverted Darlington circuitry. And like the P-3000R pre-amp, it features Amphenol AES/EBU digital connectors and employs asynchronous signal transfer over USB to support pristine playback of HD audio. On top of this, the A-9000R also incorporates separate 192 kHz/24-bit Wolfson® DACs for L/R channels, a noise-reducing DIDRC sound module, and a low-vibration chassis to minimize interference and preserve signal quality. But what sets this unit apart is its ability to be configured in any of four different amplifier modes, depending on how you want to integrate it with your other hi-fi gear. It’s that kind of versatility, married to high-end build quality, that makes the A-9000R an extremely appealing choice for the audiophile.
